I recently got a Police Force delivered by a buddy. It was in the back of his truck for a 2 hour journey. He forgot to give me the keys and mailed them to me. So I am finally ready to put the legs on and try it. I opened up the backglass and found two components that were loose in the backbox. I only see one empty spot on the boards. Maybe a component was replaced and they left the old one in there and now the new one fell out on the ride? It did work before he loaded it up. I haven't plugged it in yet. Thought I would check with the experts before I do anything. I am going to a tournament today so I can ask some other more knowledgeable players in person. I have attached some photos showing the components, boards, and empty spots.

I also noticed the display tabs have come loose in shipping. Can I just use super glue to reattach?
